A new way of making sound from the developer behind Droneo.

Tondo lets you create and manipulate audio in a new way: by painting sound on a radial sonogram. With Tondo, you can learn to create sound out of its simplest elements, and how rhythm, timbre, melody and harmony all are closely related.

The basic principle behind Tondo is that all sounds can be built by adding together very simple sounds (sinusoid waves) with varying frequencies and amplitudes. Tondo organizes this information in a way that is easy to manipulate, by painting with specialized tools. As you paint the sound , the corresponding audio is generated. At any point, you can save the information or the audio you have generated and export it in a number of ways.

Tondo can be used for making samples for other programs to use, rhythms and experimental explorations of sound.

You can export the information which defines the sound onto the clipboard, which you can then paste into documents, mail to friends, post on blogs

  1. MdG, have you tried this app, or is your comment based on the video? It looks interesting to me. I really like this guys Droneo app and it remains in my Fave Music Stuff folder, as it doesn't dictate its use (not canned), has few boundaries, and opens up a lot of doors if you take the time to dig into it. Maybe I'll give it a go….

  2. Hi folks!
    Well, you're right – Tondo _does_ sound like birds when it doesn't sound like Alexander Graham Bell and Samuel F. B. Morse. Which is another way of saying that within its fidelity range (admittedly low) it can sound like anything. I actually think Tondo sounds and looks more like a Regina Music box disk.

    If you ever do get to thinking more about birds though, I heartily recommend Donald Kroodsma's THE SINGING LIFE OF BIRDS, wherein the author had a revelatory experience when viewing sonograms of bird songs. With this visualization of the songs, a kind of universal notation, he was able to document and analyze the variations in birdsongs among various populations of the same species and other research into ancient questions such as nature/nurture behaviors, evolutionary pressures on birdsongs etc. But I digress.
    Tondo is not about sequencing or sampling, which have been adequately done by others in the past and have plenty of room for innovation in the future. Tondo doesn't make it particular easy to play Jingle Bells.
    It's about exploring the molecules of sound, compositions, timbres and rhythms, and doing so with a pretty simple interface. Other programs will show you sonograms, but mine is the first – I think – that lets you paint them and hear them as you paint in real time on an iPhone. And, the radial display of the sonogram is unique to Tondo, well suited for visualizing loops.
